 Block System Key like ALT+TAB, Ctrl+Alt+Del, Ctrl+Esc key

Hi,
Does anybody knows how to block any system keys in VB6? It has to work for
WIN95,98 and NT. I am building an online testing software, blocking these
keys is a must. I have tried some shareware ocx but it doesn't work for NT.
Any suggestion?

Iva

The example you found won't stop it in NT either.

I have been under the impression that you cannot disable CTRL+ALT+DELETE in
NT.
not via any predefined way however you could probably catch the key strokes
or something.

If I am wrong someone please let me know.

From someone with extensive C experience ... you can only do it if you were
write a new device-level driver as a replacement for the default NT one ..
the name GINA comes  to mind.
